Structural Decomposition Analysis of Domestic CO2 Emissions from Export Products of Industrial Sectors in China

This article reviews the related documents about CO₂ emission of import and export trade, and deduces and improves the input-output model to eliminate foreign influence of CO₂ emission from import product in intermediate investment. By means of two-pole decomposition method, structural decomposition analysis is conducted on changes of CO₂ emission from 1997 to 2007. It has been revealed that improvement of efficiency effect contributes to CO₂ emission reduction; reduction effect of productive structure and export structure in corporation has not yet been played, and scale effect increases CO₂ emission. At last, the policy based on in-depth calculation on carbon emission of industry sectors has been proposed.
